9d•$163,000 - $220,000

About The Position

As a Security Engineer III embedded within the Security Operations team, you will design, build, and continuously improve the technical capabilities that underpin how we detect, investigate, and respond to threats. You will work at the intersection of engineering and operations — turning security problems into scalable, automated solutions.

Requirements

Demonstrable experience working within an enterprise or corporate security function, with hands-on responsibility for protecting corporate systems, endpoints, and networks.
A solid understanding of the threat landscape facing enterprise environments and the controls used to manage risk at scale.
Practical experience with SaaS Security Posture Management tooling (e.g., Adaptive Shield, AppOmni, Obsidian Security, or Microsoft Defender for Cloud Apps) and a strong understanding of common SaaS misconfiguration risks.
Ability to communicate findings clearly and drive remediation across business and technical stakeholders.
Hands-on experience with vulnerability scanning and management platforms such as Qualys, Tenable, or Rapid7.
Familiarity with vulnerability prioritization frameworks (e.g., CVSS, EPSS, CISA KEV) and the ability to work with IT teams to drive timely and effective remediation.
Deep technical knowledge of email security controls, including SPF, DKIM, and DMARC configuration and enforcement, and experience administering enterprise email security platforms such as Proofpoint, Mimecast, or Microsoft Defender for Office 365.
Ability to investigate and respond to email-based threats and phishing incidents.
Experience deploying and managing protective DNS solutions (e.g., Cisco Umbrella, Infoblox BloxOne, Cloudflare Gateway) and web security gateways or proxies (e.g., Zscaler, Netskope, Symantec Web Security Service).
Understanding of DNS-based attack techniques and how to detect and block them.
Working knowledge of corporate network security principles, including firewall policy management, IDS/IPS, network segmentation and micro-segmentation, NAC, and Wi-Fi security.
Proven ability to administer, tune, and maintain security platforms in a production enterprise environment.
Comfort with configuring integrations between tools, managing alert workflows, and driving value from security investments through active, hands-on ownership.
Familiarity with relevant security frameworks and standards such as NIST CSF, CIS Benchmarks, and ISO 27001, and an understanding of how enterprise security controls map to compliance and audit requirements.
Strong ability to communicate technical security risks and recommended mitigations to both technical and non-technical audiences.
Comfortable working cross-functionally with IT, infrastructure, and business teams to deliver security outcomes without impeding productivity.

Nice To Haves

Experience with enterprise network security vendors such as Palo Alto Networks, Fortinet, or Cisco is beneficial.

Responsibilities

Drive the rollout and ongoing management of the company’s SSPM program, identifying and remediating misconfigurations across SaaS applications. Triage and prioritize findings, translate them into actionable remediation plans, and work closely with application owners and IT to close gaps and track resolution.
Own the endpoint vulnerability management lifecycle, from scanning and discovery through to prioritization, remediation tracking, and reporting. Collaborate with IT and infrastructure teams to ensure timely patching and configuration hardening across the endpoint estate, and provide risk-based guidance on outstanding vulnerabilities.
Design, maintain, and continuously improve the security posture of office and corporate network environments. This includes firewall policy management, network segmentation, DNS security controls, wireless security, and monitoring for anomalous traffic or lateral movement within the corporate network.
Administer and optimize email security controls to protect the organization from phishing, spoofing, malware delivery, and business email compromise. Maintain and tune anti-spam, anti-phishing, and sandboxing configurations, and ensure strong enforcement of SPF, DKIM, and DMARC policies.
Manage DNS security controls including protective DNS filtering and response policy zones to block malicious domains and prevent data exfiltration. Administer web security gateways and content filtering solutions to enforce acceptable use policies and protect users from web-based threats, both on-network and when roaming.
Take ownership of the day-to-day administration of enterprise security platforms, including configuration management, policy tuning, license management, and vendor engagement. Ensure tooling is operating effectively, alert fidelity is maintained, and platforms are integrated to provide clear visibility across the enterprise environment.
Act as a key security partner to IT, infrastructure, and enterprise technology teams, providing security guidance on new tooling deployments, system changes, and technology projects. Contribute to the broader security program by supporting risk assessments, policy development, and security awareness initiatives relevant to enterprise systems.
